VENT FOR BEER-BARRELS.

SPECIFICATION forming part of Letters Patent No. 302,577, dated July 29,188.

Application filed Jannaryllll, 1884. (No model.)

.To all whom, t may concern.'

Be it known that I, FREDRIGK H. M nwns, residing at South Chicago, inthe county of Cook and State of Illinois, and a citizen of the UnitedStates, have invented a new and useful Improvement in Vents forBeer-Barrels, of which the following is a full description, referencebeing had to the accompanying drawings, in which- Figure l is a verticallongitudinal section through the case and nozzle, showing the plungerand the receiving and discharging valve in elevation; Fig. 2, a top orplan view of the receiving and discharging valve; Fig. 3, a similar viewwith the receiving-valve removed, showing the stem of the dischargevalve in section; Fig. 4, a transverse section through the plug or' thereceiving and discharging valve, showing the form of the inletopening;Fig. 5, a section on the line x t of Fig. 2, through the plug of thereceiving and discharging valve, Fig. 6, a detail of the plate carryingthe receiving or inlet valve,

Fig. 7, a detail ofthe cover for the piston- Vtube, and Fig. S a viewshowing the vent connected with a barrel. Fig. 9 is a sectional view ofthe nozzle with only'one branch.

The object of this invention is to construct a vent for beer and otherbarrels or kegs which will do the work required in a reliable manner,and which can be readily and quickly operated, both to supply air forthe pressure and to relieve the pressure when too strong; and its natureconsists in providing a discharge? nozzle having one or more openings.in which nozzle is located a plug having an inlet and a dischargeopening, both openings being controlled by valves, and combining suchnozzle and plug with a tube and a piston or plunger, all substantiallyas hereinafter described, and

as new.

In the drawings, A represents the body of the discharge-nozzle, having,as shown, two branches, A. Each branch A has a longitudinal opening, a',communicating with a central opening in the body A, as shown in Fig. l;but in case only one nozzle or branch, as shown in Fig. 9, is used, thecentral opening, a, will be all that is required, as the nozzle can beformed by the end of the body A, if so desired. l

B is a tube or cylinder, screw-threaded at one end to receive thenozzle, the body A of which has its interior screw-th readcd to fit theend of B; or the attachment may be made in some other'suitable manner.

C is a piston, formed, as shown, of two circular disks or plates, c,between which is located a suitable packing, c', the parts being heldtogether and the packing pressed by setnuts c" on the piston-rod C,which rod passes through the cover B ot' the cylinder B, and is providedwith a suitable handle, C, ior operating purposes, and, as shown, thecover B slips onto the end ofv the cylinder B, and is provided with aseries of holes, b,to allow the air back of the pistonto escape, and hasacentral opening, b', for thc passage of the rod C.

D is aplug corresponding in diameter to the diameter of the interioropening in Jthe body A, and resting, as shown, on a shoulder, j, betweenwhich shoulder and the plug is a packing-ring, 7c, and when in place thering is made airtight by suitablegaskcts, Z. This plug has an opening,d, formed as shown in Fig. 4, which opening communicates with anopening, d', in the shell or body A for the passage of the air into thecylinder B, and the plug is also provided with a second opening, f,passing through the plug, as shown in Figs. Sand 5.

E isa plate having on one side a tongue, e, and on the other twotongues, e, leaving an opening, e, between them. The tongue e carriesthe packing h, and is arranged to have such packing cover and close theopening d in the plug, and, as shown, the plate is supported on theother side by a packing, It.

Fis a stein, the body of which passes through the openingfin the plug D,and, as shown, the portion which lies within the opening when the partsare in working order is square or,

rectangular in cross-section, so as to leave openings on each side, asshown in Fig. 3, and the opening f 1s covered andclosed by apacking-ring, located between the plug D and the head f of the stem, asshown in Figs.l 4 and 5.

G is a coiled spring located around the body of the stem F, whichprojects beyond the face of the plug between a head or nut, g, on theend of the stem and the plate E, which spring acts to hold the packingj" down to close the opening, except as the stem F is pushed endwiseagainst the resistance of the springu As IOO I is a vent-plug having anozzle, I', the plug I having an opening, i, and the nozzle l anopening, t', which openings communicate with each other.

J is a section of the barrel in which the vent-plug I is located, andwhen the parts are in position for ,use the hose H is connected -withthe Ydischarge-nozzle A and the nozzle I', as shown in Fig. S, so thatthe air can be l escape through the opening f around .the stem forcedinto the barrel or keg.

The operation is as follows: The hoseis connected with thedischarge-plug and with the vent-plug in the barrel or keg, forming acommunication between the air-supplying device andthe barrel or keg. Asthe plunger C is drawn up, fair enters the cylinder or tube B throughthe openings cl'd, the drawing up of the plunger or piston raising theplate E and the packing h to allow the air to enter, and when the pistonor plunger is pushed down the plate E and/,packing It are forced down,closing the opening d, and allowing the air to F and to enterthe'discharge-nozzle through the openings c a, to be forced into thehose,

and thence through the vent-plug into the barrel or keg, the pressure ofthe air, as the piston is forced down, forcing out the packing j" toallow the air to escape, and when the air in the cylinder is dischargedand the plunger is drawn up the spring D acts and draws the packing fdown to close the opening, While the air. enters through the opening dd. The device is to be operated to the extent required to produce thenecessary pressure in the barrel or keg. In case there is too muchpressure of gas in the barrel or keg, the plunger can be pushed down soas to engage the end ofthe stem F and open the passage f, .allowing the'gas to escape through the vent and the hose into the discharge-nozzle,and thence into the cylinder.

Vhat I claim as new, and desire to secure by Letters Patent, is-

l. The discharge-nozzle A, tube or cylinder B, and piston or plunger C,in combination with a plug, D, having an inlet-opening andadiseharge-opening,both controlled by valves, substantially as and forthe purposes specified.

2. The combination, with tube B,provided with cover B, having openingsb, the plunger C in said tube, and discharge-nozzle A, having openingd', and secured to said tube, of the plug D, havingl an inlet, d, andoutlet f, and provided with stein F, plate E, and packing h and f,substantially as described.

3. The combination, with tube B, )rovided with cover B, having openingsb, the plunger C in said tube, and discharge-nozzle A, having openingd', and secured to said tube, of the plug D, having an inlet, d, andoutlet f, and provided with stam F, plate E, packing h and j", andspring G, substantially as described.
